What are BioBags made out of?

2023-10-12

BioBags are a sustainable alternative to traditional plastic bags as they are made from natural materials that are biodegradable and compostable. These bags are considered an essential solution to the rising environmental concerns caused by plastic pollution. In this article, we will explore what BioBags are made out of and how they contribute to a greener future.

BioBags are typically made from a biopolymer called Mater-Bi, which is derived primarily from corn starch. This biopolymer is produced by the Italian company Novamont. It is a renewable resource, as corn is an agricultural crop and can be grown seasonally. Mater-Bi is also capable of breaking down naturally, making it an environmentally friendly option.

The corn starch used to make Mater-Bi is extracted from the kernels of corn. This corn starch undergoes a process called fermentation, in which microorganisms break it down into lactic acid. Through a series of chemical reactions, the lactic acid is then transformed into a polymer known as polyhydroxyalkanoate (PHA). This PHA is the main component of Mater-Bi and provides the bag with its necessary properties.

PHAs are a group of polymers that occur naturally in many microorganisms. They are carbon-neutral and do not release harmful greenhouse gases during their production. This makes them an ideal choice for creating sustainable materials. PHA bioplastics, such as Mater-Bi, have a similar performance to traditional plastics, but without the negative environmental impact.

In addition to corn starch and PHA, BioBags also contain small amounts of other biodegradable polymers, such as polyethylene glycol (PEG), plasticizers, and natural minerals. The plasticizers help to improve the flexibility and stretchability of the bags, while the minerals provide stability and strength. These components work together to create a durable yet biodegradable bag that is suitable for various packaging needs.

BioBags are not only biodegradable but also compostable. This means that under the right conditions, they can break down into organic matter, leaving behind no harmful residues. However, it is important to note that BioBags require specific composting conditions to fully decompose. They need to be processed in industrial composting facilities where temperature, humidity, and microbial activity can facilitate their decomposition. Composting at home may not provide the necessary environment for BioBags to break down efficiently.

One of the key advantages of BioBags is their reduced impact on landfills. Traditional plastic bags take hundreds of years to decompose, contributing to the accumulation of non-biodegradable waste. BioBags, on the other hand, decompose within months, significantly reducing the environmental burden. Moreover, when BioBags decompose, they do not release toxic substances or microplastics into the environment, making them a safer alternative.

BioBags are a versatile and sustainable packaging solution that can be used in various industries, including food packaging, waste management, and agriculture. They can be found in different forms like shopping bags, produce bags, and even dog waste bags. By adopting BioBags, businesses and individuals can contribute to the reduction of plastic waste and promote a more circular economy.

In conclusion, BioBags are made primarily from Mater-Bi, a biopolymer derived from corn starch. This material is renewable, biodegradable, and compostable. The inclusion of other biodegradable polymers, plasticizers, and minerals enhances the bag's performance, making it a suitable alternative to traditional plastic bags. BioBags decompose within months, reducing the impact on landfills and minimizing pollution. By utilizing BioBags, we can take a step towards a greener future and combat the global plastic pollution crisis.
